Biosphere reserve offers ideal summer holiday destination

Pu Mat National Park, located in the central province of Nghe An and classified as a World Biosphere Reserve (the largest in Southeast Asia) by UNESCO in April, has long been known for its bio-diversity.
Covering 1.3 million ha, the park includes the Pu Huong and Pu Hoat reserve zones, creating a 500km green corridor along side the Viet Nam – Lao border.
Le Thanh Do, responsible for tourism promotion of the park, told the Viet Nam News that the park received around 9,000 visitors per year on average.
"The high peak tourism season falls between April and September," he said adding, "two thirds of tourists are foreigners."
In co-operation with local tourism agencies, the park has developed a tourist map linking Cua Lo Beach, Kim Lien Village (hometown of President Ho Chi Minh) and Pu Mat National Park.
Do said that, apart from the 30 rooms for rent inside the park itself and hundreds of privately-owned hotels in nearby Con Cuong Town centre, additional accommodation and entertainment services were essential in managing greater tourist numbers.
Established in 2001, Pu Mat park hosts 896 different species of plants, 220 valuable herbs, hundreds of vegetables and fruits, 241 types of mammals, 137 types of birds and 25 types of reptiles. The forest is also the habitat of the largest herd of elephants in Viet Nam as well as endangered animals such as the sao la (a rare species of twin-horned wild cattle), tiger, panther and leopard.
Khe Kem Waterfall
Located 25km from Con Cuong Town, the 500m high Khe Kem Waterfall has always been popular among tourists, resembling a white silk scarf against the green canopy of the forest.
"Although I've visited the forest during each season of the year," said Hai Nhu, a student from the central city of Vinh. "I am always freshly astonished by the plant life."
Large, flat stones at the foot of the fall offer ideal resting places for tourists sheltering in a cooling 200C heat, Nhu added.
Violet flower valley
Lying 40km from the park main office along the Tuong Duong - Ky Son route, the peaceful valley is covered by thousands of 20-40m high sang le trees, which belong to the family of bang lang (Lagerstroemia speciosa).
"The valley, filled with violet blossoms in summer, has inspired countless poems and songs based on the romantic beauty of its green and whitish grey colours," Do said, adding that, "although many have called it the Green Valley, he preferred the name Violet Flower Valley."
The Sang Le forest hosts both recognisable and unknown trees, luring both domestic and foreign scientists, according to Do.
The forest, currently covering 70ha, will expand to 300ha under new park management plans, help protect local residents against flooding, prevent soil erosion and save water for community consumption.
Nguyen Thanh Nhan, director of Pu Mat National Park, said that local Thai ethnic minority from nearby Quang Thinh Village, which tourists are allowed to visit along with close lying caves, have done much to protect the Sang Le forest.
According to Nhan, the park presents a perfect backdrop for preserving the traditional weaving art, dance and gong playing of the Thai; the art of playing lip instruments and bamboo flutes by the Mong; water rice agriculture of the Tay Poong; sitting-sleeping customs of the Dan Lai and traditional dancing and singing of the Kho Mu.
As many as seven ethnic groups with a combined population of more than 800,000 were currently living in the park, Nhan added.
Ho Duc Phoc, chairman of the Nghe An Province People's Committee, admitted that local authorities faced a problem in creating a balance between preserving biodiversity and natural resources, promoting social economic development and maintaining the traditional cultural values of local ethnic groups.
A forest legend
Legend tells of a tree growing deep inside the forest whose bark cannot be destroyed by termites or insects such as cockroaches, spiders and mosquitoes that fear the smell of its wood, used by the Mong to build their extremely durable houses.
In 2004, Tran Xuan Cuong, head of the park's Science Research Department, conducted research into the characteristics of the sa mu dau (Cunninghamia Konishii Hayata), in order to obtain heritage status for these species of trees, of which 60 were discovered.
The largest among those discovered, designated as a Heritage Tree of Viet Nam last December, reached 70m in height, its trunk 23.7m in circumference with a diameter of 5.5m.
Cuong confirmed that these trees, only appearing at 900m above sea level in humid hilly soil, were difficult to reproduce naturally, park scientists having tried but failed many times.
"Although we continue to try and grow more trees, we have still to succeed," Cuong said.
